FEATURES
DESCRIPTIO
The LT®1126 dual and LT1127 quad are high perfor-
mance, decompensated op amps that offer higher slew
rate and bandwidth than the LT1124 dual and the LT1125
quad operational amplifiers. The enhanced AC perfor-
mance is available without degrading DC specs of the
LT1124/LT1125. Both LT1126/LT1127 are stable in a gain
of 10 or more.
■
100% Tested Low Voltage Noise: 2.7nV/√Hz Typ,
4.2nV/√Hz Max
■
Slew Rate: 11V/µs Typ
■
Gain-Bandwidth Product: 65MHz Typ
Offset Voltage, Prime Grade: 70µV Max
■
Low Grade: 100µV Max
■
High Voltage Gain: 5 Million Min
■
Supply Current Per Amplifier: 3.1mA Max
In the design, processing and testing of the device, par-
ticular attention has been paid to the optimization of the
entire distribution of several key parameters. Slew rate,
gain-bandwidth and 1kHz noise are 100% tested for each
individual amplifier. Consequently, the specifications of
eventhelowestcostgrades(theLT1126CandtheLT1127C)
have been enhanced.

Two and Three Op Amp Instrumentation Amplifiers
Power consumption of the dual LT1126 is less than one
halfoftwoOP-37s.Lowpowerandhighperformanceinan
8-pin SO package makes the LT1126 a first choice for
surface mounted systems and where board space is
restricted.

Note 8: 0.1Hz to 10Hz noise can be inferred from the 10Hz noise voltage
density test. See the test circuit and frequency response curve for 0.1Hz to
10Hz tester in the Applications Information section of the LT1007 or
LT1028 datasheets.
Note 2: Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifiers; i.e., out of 100 LT1127s (or 100
LT1126s) typically 240 op amps (or 120) will be better than the indicated
specification.
Note 3: This parameter is 100% tested for each individual amplifier.
Note 4: This parameter is sample tested only.
Note 9: This parameter is guaranteed but not tested.
Note 10: The LT1126/LT1127 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at –40°C and at
85°C. Guaranteed I grade parts are available. Consult factory.
Note 5: This parameter is not 100% tested.
Note 6: The inputs are protected by back-to-back diodes. Current limiting
resistors are not used in order to achieve low noise. If differential input
voltage exceeds ±1.4V, the input current should be limited to 25mA.

Matching Specifications
Some specifications are guaranteed by definition. For
example, 70µV maximum offset voltage implies that mis-
match cannot be more than 140µV. 112dB (= 2.5µV/V)
CMRR means that worst case CMRR match is 106dB
(5µV/V). However, the following table can be used to
estimatetheexpectedmatchingperformancebetweenthe
two sides of the LT1126, and between amplifiers A and D,
and between amplifiers B and C of the LT1127.
In many applications the performance of a system de-
pends on the matching between two op amps, rather than
the individual characteristics of the two devices. The three

APPLICATIO S I FOR ATIO
High Speed Operation
with RS and RF in the kilohm range, this pole can create
excess phase shift and even oscillation. A small capacitor
(CF) in parallel with RF eliminates this problem. With
RS (CS + CIN) = RF CF, the effect of the feedback pole is
completely removed.
When the feedback around the op amp is resistive (RF), a
pole will be created with RF, the source resistance and
capacitance (RS, CS), and the amplifier input capacitance
(CIN ≈ 2pF). In low closed loop gain configurations and
